Ice storm arrives Monday with flooding rains

An ice storm warning has been issued for our northern counties. Dodge, Fond du Lac and Sheboygan Counties are under the ice storm warning starting at 3 p.m. Monday and lasting until 6 p.m. Tuesday. These counties could see a few tenths of ice. In addition, a winter weather advisory has been issued for Washington County also for the possibility of minor icing.

Rain will start to move in after the Monday morning commute. By mid-afternoon temperatures will cool in northern communities where the rain will switch to freezing rain.

Freezing rain will stick around Monday night and most of Tuesday for northern communities, while southern spots see heavy rain and even a few thunderstorms. As the storm wraps up everyone could see a little light icy mix Tuesday evening. Counties under the ice storm warning will see over a quarter inch of ice with the advisory areas getting around a tenth.

As with any winter storm, any changes in the track could make a big difference. If the storm goes north we will see less freezing rain but a better chance for flooding. If the storm goes south the area of freezing rain will move into Milwaukee and Waukesha and some northern counties could see a little snow.

Heavy rain will be the big story for southern counties where 2-3" of rain is likely and over 2" is possible, especially in thunderstorms that develop.

Due to the heavy rain, combined with a frozen ground and snow melt, a flood watch has been issued for Jefferson, Waukesha, Milwaukee, Walworth, Racine and Kenosha Counties.

With any significant ice that develops widespread power outages and downed trees are possible. Ice will remain the biggest threat but heavy rains could cause issues as well. Cold and wind will not be factors.
